Upgrading from an older version is smoother: presets that were built on a printer or filament that has since been renamed or removed now load correctly, so you should see far fewer "missing preset" warnings. Cloud sync gets several fixes too — filament settings you had turned off no longer switch themselves back on, sync messages now tell you exactly which preset is involved, and running two copies of OrcaSlicer signed into the same account no longer logs you out at random. Installing and updating the Bambu network plugin is reliable again, including when you switch versions on Windows. On top of that, this release fixes several crashes (rotating the prime tower, using the Measure tool, and running a Pressure Advance calibration), a couple of slicing and print-time-estimate problems, and Reload from Disk for STEP models after you reopen a project. New this time: a filename placeholder for the first object's name, clickable wiki links in the Preferences dialog, and add:north filament profiles. **OrcaSlicer is also available on the Microsoft Store for Windows users here: [Microsoft Store Link](https://apps.microsoft.com/detail/9MV6GL23XM59?hl=en-us&gl=SG&ocid=pdpshare)** **For Linux users, it is available on Flathub: [Flathub Link](https://flathub.org/en/apps/com.orcaslicer.OrcaSlicer)** #### 🌊 New Features & Improvements * **`{first_object_name}` filename placeholder** by @raistlin7447 in [14497](https://github.com/OrcaSlicer/OrcaSlicer/pull/14497) Adds a new `{first_object_name}` placeholder you can put in the output filename format — it fills in the name of the first printable object on the plate. In older versions the default `{input_filename_base}` would sometimes fall back to the first object's name; that was corrected earlier, but some people had relied on it to get the part name into their file names. This placeholder brings that option back, and it changes nothing unless you add it to your format. Closes #14493 and #14513. first_object_name filename placeholder * **Wiki links and a tidier Preferences dialog** by @yw4z in [13857](https://github.com/OrcaSlicer/OrcaSlicer/pull/13857) The Preferences dialog now shows clickable "Wiki" links next to settings — the same as in the sidebar — so you can open the relevant documentation in one click. It's also reorganized so related options sit together (Draco export quality under Project, the shared-profiles notification under Preset, filament sync mode next to auto-sync), combo boxes now have tooltips, there's a new "Experimental features" section under Developer, and the network-plugin Reload button has moved here from the Developer tab. Wiki link support in the Preferences dialog * **Use number-or-percentage settings in custom G-code** by @Noisyfox in [14526](https://github.com/OrcaSlicer/OrcaSlicer/pull/14526) Some settings can be entered either as a fixed number or as a percentage. Custom G-code can now read these values; before, referring to one of them returned nothing. Fixes #14522. * **Name the preset in cloud-sync messages** by @SoftFever in [14592](https://github.com/OrcaSlicer/OrcaSlicer/pull/14592) When cloud sync reports a conflict, asks you to confirm a force-push, or says a preset is too large to sync, the message now names the specific preset involved instead of leaving you to guess which one it means. #### 🛠️ Bug Fixes ##### Profiles & presets * **Repair presets that pointed at renamed or deleted profiles** by @SoftFever in [14595](https://github.com/OrcaSlicer/OrcaSlicer/pull/14595) Fixes user _[Truncated at 4000 characters — full notes: https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/v2.4.2]_ ### v2.4.1 — OrcaSlicer v2.4.1 Official Release - Date: 2026-06-28 - Version: v2.4.1 - Original notes: https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/v2.4.1 - Permalink: https://whatsnew.fyi/product/orcaslicer/releases/v2.4.1 - **added** — Native Windows ARM64 build for Snapdragon X Elite and other Windows ARM64 devices with full feature parity including STEP/STP import, SVG→3D, and text emboss - **added** — Minimal chamber temperature field per filament alongside the existing Target value, exposed to print-start macros as the chamber_minimal_temperature variable - **added** — Snapmaker U1 nozzle profiles - **added** — Elegoo Centauri 2 support - **changed** — Windows x64 installer and portable downloads now carry an _x64 suffix in filenames to distinguish them from ARM64 ones - **changed** — Reworked skirt and brim generation into a single shared flow with improved tracking per group and print height - **changed** — By Layer mode with per-object skirts now prints in order skirt → brim → object for each object - **changed** — Profile-sync behavior now includes a one-time warning dialog explaining the behavior change introduced in 2.4.0 - **changed** — 3MF uploads now include a plateindex field to specify which plate to print when sending packaged .gcode.3mf jobs - **fixed** — Fixed regression in 2.4.0 where skirt was re-printed before each object during per-object and sequential printing - **fixed** — Fixed skirt re-printing issue that could knock already-printed parts off the plate - **fixed** — Fixed object print order not being respected with skirts enabled in By Object mode - **fixed** — Fixed draft shield generation at Skirt height = 0 - **fixed** — Fixed draft shield overlapping the brim - **fixed** — Fixed unsafe By Object configurations by rejecting them with a clear slicing error - **fixed** — Restored missing or miscategorized filaments in the Orca Filament Library and filament selection dialog - **fixed** — De-duplicated profile setting IDs - **fixed** — Corrected ambiguous AMS filament matches - **fixed** — Improved resolution of renamed and inherited presets - **fixed** — Fixed fuzzy skin issues - **fixed** — Fixed AMS sync ordering - **fixed** — Fixed CrealityPrint hosts compatibility - **fixed** — Fixed Linux Wayland rendering #### What's Changed This is the OrcaSlicer V2.4.1 release — a maintenance update on top of 2.4.0 with a broad round of profile and preset fixes at its core: it restores filaments that had gone missing or were miscategorized in the Orca Filament Library and the filament selection dialog, de-duplicates profile setting IDs, corrects ambiguous AMS filament matches, and improves how renamed and inherited presets are resolved. Other changes include a native Windows ARM64 build, a new minimal chamber temperature field, and a reworked skirt and brim generator (fixing a 2.4.0 regression that re-printed the skirt during per-object/sequential printing), alongside fixes for fuzzy skin, AMS sync ordering, CrealityPrint hosts, and Linux Wayland rendering. It also adds Snapmaker U1 nozzle profiles, Elegoo Centauri 2 support, and a refreshed translation catalog. #### 🌊 New Features & Improvements * **Native Windows ARM64 build (Snapdragon X Elite)** by @abehrman in [14059](https://github.com/OrcaSlicer/OrcaSlicer/pull/14059), brought up to date and merged by @SoftFever in [14381](https://github.com/OrcaSlicer/OrcaSlicer/pull/14381) Adds a green, native Windows-on-ARM build (not x64 under emulation) for Snapdragon X Elite and other Windows ARM64 devices, folded into the standard Windows build matrix. It ships full feature parity — STEP/STP import, SVG→3D, and text emboss all build and work on ARM64 — with the x64/x86 build paths unchanged. This is a build/CI addition; wiring ARM64 into the official signed-release pipeline (code signing, installer) is a follow-up. The original work and authorship are @abehrman's (#14059); #14381 simply brings that branch up to date with `main`. With the new ARM64 builds, the Windows x64 installer and portable downloads now carry an `_x64` suffix in their filenames to distinguish them from the ARM64 ones. * **Minimal chamber temperature field** by @igiannakas in [14340](https://github.com/OrcaSlicer/OrcaSlicer/pull/14340) Adds a per-filament "Minimal" chamber temperature alongside the existing value (now labelled "Target") in the filament settings, exposed to print-start macros as the `chamber_minimal_temperature` variable. This lets a start macro begin printing once the chamber reaches a threshold — for example, start at 50 °C while the chamber keeps heating toward a 60 °C target. The value is validated against the target (it warns and clamps if set higher) and is not emitted via M141/M191; it defaults to zero for existing profiles. Minimal and Target chamber temperature fields * **Skirt and brim generation rework** by @kisslorand in [14333](https://github.com/OrcaSlicer/OrcaSlicer/pull/14333) Reworks skirt and brim generation into a single, shared flow and **fixes a regression introduced by the 2.4.0 skirt overhaul** affecting per-object and sequential (*By Object*) printing: with a skirt enabled, the skirt could be re-printed before each object — running the nozzle back over it, or even knocking already-printed parts off the plate — and the object print order was not respected. Skirts are now tracked per group and per print height so each one prints exactly once. In *By Layer* mode with per-object skirts, the order is now skirt → brim → object for each object (previously all skirts printed first), and brims print together with the object or group they belong to while *Combine brims* still merges touching brims. Draft shields are generated through the same logic, fixing cases where a draft shield failed to generate at *Skirt height = 0* or overlapped the brim. Unsafe *By Object* configurations that would need a shared multi-layer skirt or draft shield are now rejected with a clear slicing error. Fixes #14319 and #14366. | Before | After | |--------|-------| | Use 3MF instead of G-code option * **Microsoft Store (MSIX) install channel for Windows** by @SoftFever in [14142](https://github.com/OrcaSlicer/OrcaSlicer/pull/14142) Adds a Microsoft Store MSIX package as a new Windows install channel, built by CI from the same install tree as the existing installer. This gives Windows 11 users a channel that works under Smart App Control — which otherwise blocks the unsigned GitHub installer — with the Store handling signing. In the packaged build, the update dialog points to the Microsoft Store instead of the GitHub release page, and file/URL associations are managed through Windows' Default Apps settings; configuration still lives in `%APPDATA%\OrcaSlicer` and is shared with classic installs. The classic NSIS installer and portable builds are unchanged. **Note:** the Store submission is still going through Microsoft's certification review, so the listing isn't publicly available yet — it will appear on the Microsoft Store once approved. Until then, install this release using the classic installer or portable builds as usual. OrcaSlicer on the Microsoft Store * **Stay logged in to Orca Cloud while offline** by @Noisyfox in [14235](https://github.com/OrcaSlicer/OrcaSlicer/pull/14235) Orca Cloud session information is now stored locally (in the system keystore where available, otherwise encrypted with a per-machine key), so you can keep using Orca and your custom profiles while offline. Previously, having no internet connection — or even a brief network glitch at startup — would log you out automatically and make your profiles unavailable. Note that switching back to an older OrcaSlicer version after using _[Truncated at 4000 characters — full notes: https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/v2.4.0]_ ### v2.4.0-beta — OrcaSlicer V2.4.0 Beta release - Date: 2026-06-09 - Version: v2.4.0-beta - Original notes: https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/v2.4.0-beta - Permalink: https://whatsnew.fyi/product/orcaslicer/releases/v2.4.0-beta - Labels: Pre-release - **added** — Add realistic rendering with Phong shading, ambient occlusion (SSAO), and cast shadows to the 3D canvas - **added** — Add configurable lightning infill angles for overhang, prune, and straightening control in expert mode - **added** — Add double-click on object list rows to frame the item in the 3D view - **changed** — Overhaul preview sliders with interactive layer labels, improved visual styling, and unified single-layer and multi-layer preview appearance - **added** — Add Troubleshoot Center in Help menu for diagnostics, log management, system information collection, and profile rebuilding - **changed** — Improve bridging stability and quality - **changed** — Enhance per-feature filament assignment for multi-material prints - **changed** — Improve overall stability and speed #### What's Changed This is the OrcaSlicer V2.4.0 Beta. A lot of effort has gone into this release to improve stability, speed, and print quality, along with the interface and printer support. Bridging in particular has been greatly improved by @ianalexis, @kisslorand, and many others, and a new realistic rendering option from @RF47 makes your models look gorgeous right inside OrcaSlicer. There's good news for multi-material users too: per-feature filament assignment got a big upgrade, opening up much more creative prints. Ever thought about printing the outer walls in TPU and the rest in PLA? Now you can — check out the details below. **Note:** Everything from the 2.4.0 Alpha — Orca Cloud, Z Anti-Aliasing (ZAA) contouring, Machine Input Shaping, Optimized Gyroid infill, and the redesigned printer selection dialog — is included in this build. See the [2.4.0 Alpha release notes](https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/v2.4.0-alpha) for details on those. #### 🌊 New Features & Improvements * **Realistic View: Phong shading, ambient occlusion, and cast shadows** by @RF47 in [13704](https://github.com/OrcaSlicer/OrcaSlicer/pull/13704) Adds a new set of rendering options to the 3D canvas, letting you switch between the classic Gouraud shader and a new Phong shader and layer on SSAO ambient occlusion and cast shadows. The result is a far more realistic, depth-rich preview of your models. Reflections (Phong) and cast shadows are available in prepare mode. | Gouraud | Gouraud + SSAO | Gouraud + SSAO + Shadows | |---------|----------------|--------------------------| | | | | | Phong | Phong + SSAO | Phong + SSAO + Cast Shadows | |-------|--------------|-----------------------------| | | | | Reflections menu * **Configurable lightning infill angles** by @RF47 in [13848](https://github.com/OrcaSlicer/OrcaSlicer/pull/13848), with wiki documentation by @ianalexis in [13984](https://github.com/OrcaSlicer/OrcaSlicer/pull/13984) Exposes three new expert-mode settings for lightning infill: the overhang angle (how far walls can support the layer above), the prune angle (how aggressively short unsupported branches are removed), and the straightening angle (how far branches can be simplified). These give finer control over how lightning infill is generated. Fixes #13758. Lightning infill angle settings | Overhang | Prune | Straightening | |--------|--------|--------| | | | | * **Double-click an object list row to frame it in the 3D view** by @RJAudas in [13804](https://github.com/OrcaSlicer/OrcaSlicer/pull/13804) Adds Blender-style "Frame Selected" behavior to the object list: double-clicking an object, part, or instance row in the left panel now frames that item in the 3D vie _[Truncated at 4000 characters — full notes: https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/v2.4.0-beta]_ ### v2.4.0-alpha — OrcaSlicer V2.4.0 Alpha release - Date: 2026-05-25 - Version: v2.4.0-alpha - Original notes: https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/v2.4.0-alpha - Permalink: https://whatsnew.fyi/product/orcaslicer/releases/v2.4.0-alpha - Labels: Pre-release - **added** — Orca Cloud platform for profile sync, preset bundle sharing, and community discovery - **added** — Profile synchronization across machines through Orca Cloud account login - **added** — Profile version history tracking and rollback functionality in Orca Cloud - **added** — Shareable preset bundles with descriptions, images, version info, and compatible printer metadata - **added** — Community Explore feature to browse and subscribe to publicly shared preset bundles - **added** — Z Anti-Aliasing (ZAA) contouring for smoother top surfaces - **added** — Expert user mode - **added** — Native Wayland support for Linux - **added** — Machine Input Shaping - **added** — Optimized Gyroid infill - **added** — Prusa-style combined brims - **changed** — Redesigned printer selection dialog #### What's Changed This is the OrcaSlicer V2.4.0 Alpha release. The headline feature is **Orca Cloud** — a new centralized platform for profile sync, preset bundle sharing, and community discovery at cloud.orcaslicer.com. This release also introduces **Z Anti-Aliasing (ZAA) contouring** for smoother top surfaces, an Expert user mode, native Wayland support for Linux, Machine Input Shaping, Optimized Gyroid infill, Prusa-style combined brims, a redesigned printer selection dialog, and a large number of bug fixes and profile updates. **Note:** Please check #13828 for known issues. #### ☁️ Orca Cloud Orca Cloud is now live at [cloud.orcaslicer.com](https://cloud.orcaslicer.com) — a centralized platform that brings your 3D printing workflow online. It keeps your printer, filament, and process profiles synchronized across every machine you use, lets you share finely tuned preset bundles with the community, and helps you discover configurations created by fellow makers around the world. Think of it as the connective tissue between your slicer, your profiles, and the broader OrcaSlicer ecosystem — no more manually copying config files between computers or hunting through forums for the right profile. **Note:** Orca Cloud is optional. Local profiles and existing OrcaSlicer workflows continue to work as before. You can keep using OrcaSlicer without logging in to Orca Cloud. **Open ecosystem:** Orca Cloud is part of our long-term vision for an open 3D printing ecosystem. We want OrcaSlicer to connect users, contributors, printer manufacturers, filament makers, and hardware/software partners through shared profiles, better compatibility data, and smoother workflows. We welcome users, makers, manufacturers, and partners to join, integrate, and collaborate with us to build an ecosystem that benefits the whole community and the wider 3D printing industry. This is just the beginning. We have many more features planned for Orca Cloud and the broader OrcaSlicer ecosystem. Orca Cloud is designed with privacy in mind. Data is currently hosted in the USA. In the future, we plan to add more region-specific servers and allow users to choose their preferred data center location for improved performance, data residency, and privacy needs. * **Orca Cloud — Profile Sync, Version History, Preset Bundles, and Community Sharing** https://github.com/OrcaSlicer/OrcaSlicer/pull/13414 **Profile Sync:** Log in to OrcaSlicer with your Orca Cloud account, and your printer, filament, and process profiles sync automatically across machines. You can also view and manage all synced profiles from the Orca Cloud web interface. Orca Cloud profile sync interface **Profile Version History:** Your cloud-backed profiles support version history on Orca Cloud. Mark milestones, track what changed, and revert to a previous version whenever you need — useful for recovering from a tuning session that did not work out, or rolling back to a known-good configuration before an important print. Orca Cloud profile version history **Preset Bundles:** Create shareable preset bundles with descriptions, images, version info, and compatible printer metadata. Publish them publicly for the community to discover, or keep them private and share only with specific collaborators. Orca Cloud preset bundle editor **Community Explore:** Browse public bundles shared by the community on the Orca Cloud website. Subscribe to bundles you like and they will sync to your slicer automatically, with update notifications when the author publishes a new ve _[Truncated at 4000 characters — full notes: https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/v2.4.0-alpha]_ ### v2.3.2 — OrcaSlicer V2.3.2 Official Release - Date: 2026-03-23 - Version: v2.3.2 - Original notes: https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/v2.3.2 - Permalink: https://whatsnew.fyi/product/orcaslicer/releases/v2.3.2 - **security** — Fixed a vulnerability where a crafted .3mf file could write to arbitrary filesystem locations via path traversal during import - **added** — Add a configurable wipe tower type setting at printer level instead of being determined solely by printer model - **added** — Extend tooltip default-value display to Percent, FloatOrPercent, String, and Bool config option types - **added** — Improve MMU detection via Moonraker database with normalized detection for Happy Hare and more reliable multi-material system detection - **added** — Allow cancellation during beam interlocking generation - **changed** — Title bar now dynamically expands to use all available space, supporting long project names with ellipsis truncation - **changed** — Main tabs now automatically collapse to icon-only mode when the window is too small, ensuring Slice/Print buttons remain visible - **added** — Snapmaker Printer Agent now recognizes esthetic filament sub-types (wood-infused, matte, marble) for better profile matching - **changed** — Move adaptive flowrate setting to developer mode with clarified tooltip noting it is experimental - **fixed** — Fix dirty flags not showing for extruder-specific options, crash when switching to non-first extruder tabs, and parameters on one extruder affecting others - **fixed** — Fix crash during G-code export for multi-material prints using WipeTower2 where mesh data was not initialized - **fixed** — Fix wipe tower being placed beyond bed boundary after printer preset changes by re-clamping tower position and including brim in estimated size - **fixed** — Skip flushing volume validation for multi-tool printers and add validation for conflicts between precise Z height and prime tower settings - **fixed** — Fix CLI segfault when using --info, --slice, or --export-3mf caused by render-data code dereferencing NULL plater pointer in CLI mode - **changed** — Improve Linux experience with titlebar and related fixes #### What's Changed This is OrcaSlicer V2.3.2, the stable release. This release addresses a security vulnerability in 3MF file import, adds a configurable wipe tower type setting, delivers extensive Linux and Flatpak improvements, fixes a CLI segfault, and includes UI refinements like dynamic title bar sizing and accordion sidebar tabs. > [!NOTE] > **For Linux users:** The official Flathub version is now available. You can install it with this command: `flatpak install flathub com.orcaslicer.OrcaSlicer` For features introduced earlier in the v2.3.2 cycle, please refer to: [v2.3.2-beta](https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/v2.3.2-beta) · [v2.3.2-beta2](https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/v2.3.2-beta2) · [v2.3.2-rc](https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/v2.3.2-rc) · [v2.3.2-rc2](https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/v2.3.2-rc2) #### 🌊 New Features & Improvements * **Configurable wipe tower type** by @SoftFever in https://github.com/OrcaSlicer/OrcaSlicer/pull/12781 Adds a new printer-level setting to select the wipe tower type, instead of it being determined solely by the printer model. Type 2 is generally recommended for MMU, filament cutter, and tool changer setups. Wipe tower type setting * **Default values in tooltips for more option types** by @valerii-bokhan in https://github.com/OrcaSlicer/OrcaSlicer/pull/12508 Extends the tooltip default-value display (introduced in RC) to Percent, FloatOrPercent, String, and Bool config option types. Default values are sourced from parent profiles rather than hardcoded Orca defaults. Default values in tooltips * **Improved MMU detection via Moonraker database** by @ammmze in https://github.com/OrcaSlicer/OrcaSlicer/pull/12764 Happy Hare now writes MMU lane data to the Moonraker database (similar to AFC), so detection has been normalized. The Moonraker database is checked first, providing more reliable multi-material system detection and access to vendor name data. * **Allow cancellation during beam interlocking generation** by @Noisyfox in https://github.com/OrcaSlicer/OrcaSlicer/pull/12759 Beam interlocking generation can now be cancelled mid-process. Previously, certain parameter combinations could cause generation to take several minutes with no way to stop it. * **Dynamic title bar with longer project names** by @yw4z in https://github.com/OrcaSlicer/OrcaSlicer/pull/12730 The title bar now dynamically expands to use all available space, supporting long project names with ellipsis truncation. Also fixes window buttons being clipped at minimum width on Windows and a thin titlebar on Linux. Fixes #12723. ![explorer_l92JNSeq3v](https://github.com/user-attachments/assets/aa0b3ff1-c155-46b5-abc8-cf8167db18a7) * **Accordion style main tabs** by @yw4z in https://github.com/OrcaSlicer/OrcaSlicer/pull/12772 main tabs now automatically collapse to icon-only mode when the window is too small, ensuring the Slice/Print buttons always remain visible. Fixes #12723. ![Accordion sidebar tabs](https://github.com/user-attachments/assets/848331ee-0206-41a8-961f-e65e68ca5f56) * **Snapmaker esthetic filament sub-types** by @gaaat98 in https://github.com/OrcaSlicer/OrcaSlicer/pull/12699 The Snapmaker Printer Agent now recognizes esthetic filament sub-types (wood-infused, matte, marble) for better profile matching instead of falling back to generic PLA. * **Move adaptive flowrate to developer mode** by @Sabriel-Koh in https://github.com/OrcaSlicer/OrcaSlicer/pull/12688 The "Adaptive Volumetric Speed" setting is now hidden behind developer mode, with a clarified tooltip noting it is experimental. #### 🛠️ Bug Fixes _[Truncated at 4000 characters — full notes: https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/v2.3.2]_ ### v2.3.2-rc2 — OrcaSlicer V2.3.2 Release Candidate 2 - Date: 2026-03-06 - Version: v2.3.2-rc2 - Original notes: https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/v2.3.2-rc2 - Permalink: https://whatsnew.fyi/product/orcaslicer/releases/v2.3.2-rc2 - Labels: Pre-release - **changed** — Remove redundant double title bar on Linux for a cleaner UI consistent with Windows and macOS - **changed** — Prefer discrete GPU on dual-GPU Linux systems to improve 3D viewport performance - **fixed** — Fix Junction Deviation processor to prevent time estimate from being influenced by machine jerk limits and add Z-axis calculation support - **fixed** — Fix Bambu LAN printing with legacy network plugin failing with access code errors - **fixed** — Fix pressure equalizer overshooting line endpoints when processing very short movements - **fixed** — Fix fan speed not resetting to normal after ironing completes - **fixed** — Fix fuzzy skin artifacts with classic wall generator and crash when using fuzzy skin on Flatpak builds - **fixed** — Fix Emboss font search not returning results when font faces are loaded from cache on macOS - **fixed** — Fix color rendering inconsistencies on macOS by ensuring window uses sRGB color space - **fixed** — Fix DRC file loading failing when file path contains non-ASCII characters - **fixed** — Fix Celsius symbol not showing on G-code viewer - **fixed** — Fix percent sign escaping - **fixed** — Fix missing space after extruder name - **fixed** — Fix grammar and spelling errors in GUI strings #### What's Changed This is the OrcaSlicer V2.3.2 Release Candidate 2. This release brings major Linux usability improvements (no more double title bar, discrete GPU preference), fixes for Bambu LAN printing with the legacy plugin, pressure equalizer corrections, and several fuzzy skin and macOS fixes. #### 🌊 New Features & Improvements * **Linux: no more double title bar** by @SoftFever in https://github.com/OrcaSlicer/OrcaSlicer/pull/12600 Removes the redundant double title bar on Linux, bringing the look in line with Windows and macOS for a cleaner, more polished UI. | Before | After | |--------|-------| | | | * **Linux: prefer discrete GPU on dual-GPU systems** by @SoftFever in https://github.com/OrcaSlicer/OrcaSlicer/pull/12602 OrcaSlicer now automatically uses the discrete GPU on dual-GPU Linux systems, improving 3D viewport performance. * **Junction Deviation processor improvements** by @ianalexis in https://github.com/OrcaSlicer/OrcaSlicer/pull/12440 Follow-up to the JD time estimation feature: fixes a bug where the time estimate was still influenced by the machine's jerk limits even when Junction Deviation was enabled, and adds Z-axis calculation support.
